Why Is A Roof Moss Treatment Important?
Moss is a common problem on roofs in our region, and it can cause significant damage to your roof if left untreated. Here are some reasons why getting moss treatment on your roof is crucial for the health of your property:
- Prevents damage to your shingles: Moss can cause damage to your shingles by trapping moisture against the surface of your roof. This can lead to the growth of mold and mildew, which can weaken your shingles and cause them to deteriorate more quickly. Over time, this can lead to water damage to your property, which can be costly to repair. Getting moss treatment on your roof can help to prevent damage to your shingles and extend the lifespan of your roof.
- Improves energy efficiency: Moss can also affect the energy efficiency of your property. When moss accumulates on your roof, it can block the flow of air through your attic, leading to higher energy bills and reduced comfort in your home. Getting moss treatment on your roof can help to improve the energy efficiency of your property and reduce your energy costs.
- Improves curb appeal: A clean roof is an important part of maintaining the curb appeal of your property. When moss accumulates on your roof, it can create an unsightly appearance that can detract from the overall aesthetic of your property. Getting moss treatment on your roof can help to improve its appearance and make your property more attractive to potential buyers or tenants.
- Protects your investment: Your roof is one of the most important investments in your property, and getting moss treatment is a crucial part of protecting that investment. By preventing damage to your shingles and improving the energy efficiency of your property, moss treatment can help to extend the lifespan of your roof and protect your investment for years to come.
Overall, getting moss treatment on your roof is an important part of maintaining the health of your property. At our company, we use specialized equipment and techniques to safely and effectively treat moss on your roof, helping to keep it clean and healthy for years to come.

Moss Treatment Guarantee
When it comes to killing existing low level moss on your roof, we guarantee our treatments will work. This is what that process looks like:
We apply our moss treatments is in powder form, and for it to spread on your roof properly rain is necessary. Our guarantee is that you will have no bright green (live) moss on your roof (dead moss will be dark in color) 6 weeks after the first rain following the treatment.
How long the dead moss will remain on your roof depends on various factors such as roof pitch, roof type, and various environmental factors acting upon the dead moss such as rain and wind. Please note, dead moss can stay on you roof for a very long time, especially if your roof has a low pitch. We use what we call “the frisbee analogy” where we state that if you can throw a frisbee on your own roof and it will get stuck, then your roof is a type where moss is more likely to take a great deal of time to fall off. Like the frisbee, the dead moss doesn’t have a strong bond to the roof, yet unless acted upon it will not free itself.
If this does not sound like the result you want that is no issue, as we offer more immediate results with our Roof Cleaning Roof Moss Removal Service, and you can click here to learn more.

Moss Treatment FAQs
Our method is an eco-friendly white powder we strategically spread across your roof in multiple lines. It works by changing the acidity of the moss, making the environment too basic for it to live. Over time the moss dies, and any new moss that tries to grow cannot due to the environment being harsh for it until it wears off.
Moss treatment needs rain to activate, so we guarantee 6 weeks after the first rain following your treatment you will not be seeing any green moss on your roof.
No, it will not. We have treated thousands of roofs and never ran into this issue even once.
Generally once a year, but some rare places may need it more often. If you have a roof face that stays damp and never sees the sun, pay extra attention to it.
Short and simple – yes.
Yes, the roof absorbs the eco-friendly treatment and becomes an area moss considers a harsh terrain, stunting regrowth.
Treatment is the application of an eco-friendly powder, killing moss on your roof over time. Removal is the physical brushing off of the moss. Both seek the same end goal, but treatment can only kill the moss and have it stay there if your roof pitch is very flat. If you throw a frisbee on your roof and it gets stuck, your moss will be the same. It may be dead and no longer attached, but external forces need to act on it or it will remain.
That is the beauty of our moss removal system, we do it immediately after – that same day. This makes it so that we have blanket coverage to kill the moss on your roof, hitting it from all angles.
No, we can do it without anyone being home. We can even send your pictures if you’d like.
